JPLB
Electrodeposited copper foil for negative electrodes of current collectors
This foil is plain copper foil without backside nodulation and zinc-free. The passivation is a unique layer of chromium which increases shelf-life.
The foil has good adhesion to graphite slurry and provides an even thickness distribution, important for tight cell packaging.
Equivalent roughness on both sidesenables uniform coating.
JPLB is suitable for high power and high energy cells.
Available thicknesses range from 8µm to 18µm.
